Ice Machine Heat of Rejection | Manitowoc Ice S1800 specification

Installation Instructions	Section 2

Location of Ice Machine

The location selected for the ice machine must meet the following criteria. If any of these criteria are not met, select another location.

•The location must be free of airborne and other contaminants.

•The air temperature must be at least 35°F (1.6°C), but must not exceed 110°F (43.4°C).

•The location must not be near heat-generating equipment or in direct sunlight and must be protected from weather.

•The location must not obstruct air flow through or around the ice machine. Refer to the chart below for clearance requirements.

S1800M	Water-Cooled*
Top/Sides	8" (20.3 cm)
Back	5" (12.7 cm)

*There is no minimum clearance required for water-cooled or remote ice machines. This value is recommended for efficient operation and servicing only.

!Caution

The ice machine must be protected if it will be subjected to temperatures below 32°F (0°C). Failure caused by exposure to freezing temperatures is not covered by the warranty. See “Removal from Service/Winterization”.

B.T.U./Hour

Because the heat of rejection varies during the ice making cycle, the figure shown is an average.

Ice machines, like other refrigeration equipment, reject heat through the condenser. It is helpful to know the amount of heat rejected by the ice machine when sizing air conditioning equipment where self-contained air- cooled ice machines are installed.

This information is also necessary when evaluating the benefits of using water-cooled or remote condensers to reduce air conditioning loads. The amount of heat added to an air conditioned environment by an ice machine using a water-cooled or remote condenser is negligible.

Knowing the amount of heat rejected is also important when sizing a cooling tower for a water-cooled condenser. Use the peak figure for sizing the cooling tower.
